Description

  The present invention relates to an image processing apparatus capable of performing development processing on RAW image data.

  In recent years, digital cameras capable of storing RAW image data have been commercialized. Here, RAW image data refers to A / D converted signals output from an image sensor (CCD, CMOS, etc.) of a digital camera. That is, RAW image data is data before image processing is performed (hereinafter also referred to as development), and is data that can be viewed as an image for the first time after development processing. The RAW image data can be said to be “raw” data before processing.

  By the way, when RAW image data is saved by a digital camera, it is saved as a RAW file in an image recording format called RAW format. However, since the RAW format is not a standardized standard, even if the name of the same RAW format is used, the RAW file is often incompatible if the manufacturer and model of the digital camera storing the RAW file are different. Specifically, the extension, development parameter, data structure, RAW image data compression method, and the like are different. Here, the development parameter refers to various information necessary for developing RAW image data such as optical black value, white balance information, color filter arrangement information of image sensor, color space information, gradation correction information, and the like. .

  When digital development processing is performed on a RAW file saved on a digital camera using a computer, etc., if the manufacturer and model of the digital camera are different, each RAW file is not compatible, so development processing can be performed using general-purpose software. I can't. Therefore, software for developing the RAW image data included in the RAW file by a computer is prepared for each maker. When the user prints the RAW file, the RAW image data is generated by the computer using the software. In many cases, image data stored in a general-purpose storage format such as JPEG format is transferred to a printer for printing.

  On the other hand, a printer (hereinafter also referred to as direct printing) capable of printing by connecting a digital camera to a printer via a USB cable or the like, or inserting a memory card of the digital camera into a memory slot of the printer (hereinafter also referred to as direct printing). , Also called a direct printer). A technique for directly printing a RAW file stored in a digital camera using a direct printer has been studied. For example, Patent Document 1 discloses a technique for extracting JPEG image data included in a RAW file, transferring it to a printer, and performing direct printing inside a digital camera. Furthermore, a technique for enabling direct printing by developing a RAW file inside a printer has been studied.

JP-A-2005-33468

  As described above, RAW files are not compatible with different manufacturers and models of digital cameras. Therefore, when developing a RAW file within a printer, the RAW image data is developed for each RAW file. It is necessary for the printer to have necessary information (hereinafter referred to as development information). Accordingly, if the printer has development information for a specific RAW format RAW file in advance, the RAW format RAW file can be subjected to development processing inside the printer, so direct printing is performed. be able to. On the other hand, a RAW file that does not include development information cannot be directly printed because it cannot be developed inside the printer.

  For example, when the digital camera A manufactured by the manufacturer A and the digital camera B manufactured by the manufacturer B are models that can store RAW image data, the direct printer C uses the RAW file A stored by the digital camera A. Assuming that the RAW file B having development information and the RAW file B stored in the digital camera B does not have development information, the RAW file A can be directly printed using the printer C. , RAW file B cannot be directly printed.

  Therefore, when the user uses one memory card in common with the digital cameras A and B to store the RAW image data and tries to perform direct printing using the printer C, the RAW file A can be printed, but RAW file B cannot be printed. That is, when a plurality of RAW files are stored in one memory card, there are files that can be directly printed and files that cannot. In such a case, the user may feel inconvenient if it is not immediately known whether or not the RAW file stored in the memory card can be printed.

  Such a problem is a problem common to image processing apparatuses such as a photo storage and a personal computer that can perform development processing on RAW image data.

  SUMMARY An advantage of some aspects of the invention is that it improves user convenience when developing RAW image data included in a RAW file.

  SUMMARY An advantage of some aspects of the invention is to solve at least a part of the problems described above, and the invention can be implemented as the following forms or application examples.

Application Example 1 An image processing apparatus capable of performing development processing on RAW image data included in a specific RAW file,
For each RAW file acquired by the image processing device, based on the file name, a determination unit that determines whether development processing is possible or impossible in the image processing device,
The determination unit displays at least one of information on the RAW file determined to be developable in the image processing apparatus and information on the RAW file determined to be incapable of development processing in the image processing apparatus. A display unit;
An image processing apparatus comprising:

  In this specification, RAW image data includes a concept including a pixel value output from an image sensor (CCD, CMOS, etc.) of a digital camera and converted into digital data as it is, and data obtained by compressing the digital data. Say. Here, there are a lossless compression method and a lossy compression method for compression. The lossless compression method refers to a compression method in which data loss does not occur at all. When a code compressed by the lossless compression method is decoded, the data before compression can be completely restored. The lossy compression method is a method in which a part of data cannot be restored, but is compressed in a sufficiently useful form as image information. For example, there is a method of recording data in a bright place of an image by quantizing it. When compressed data in such a format is decoded, the data before compression is not completely restored, and the data in the bright place becomes discrete data. However, the gradation expression in the image data in the bright place is greatly affected. Therefore, it is possible to develop an image capable of maintaining sufficient image quality even with such a format of data.

  According to the image processing apparatus of the application example 1, for example, when the image processing apparatus includes an extension table in which at least one extension of a RAW file that can be developed by the image processing apparatus is described, Based on the extension table, whether or not each RAW file stored in the storage medium can be developed is displayed, and the name of the RAW file that can be developed and the total number of RAW files that can be developed are displayed. can do. In addition, the file names of RAW files that cannot be developed, the total number of RAW files that cannot be developed, and the like can be displayed on a display unit included in the image processing apparatus. Of course, other methods such as determination based on information such as a naming rule of a RAW file that can be developed by the image processing apparatus without using the extension table may be used.

  Accordingly, when the user looks at the display unit, among the plurality of RAW files stored in the storage medium, the file name, the number of files, etc. of the RAW file that can be developed by the image processing apparatus and the RAW file that cannot be developed. Can know. Further, since the determination is made based on the file name, it is possible to make a determination and display in a short time, which is preferable.

Application Example 2 In the image processing apparatus according to Application Example 1,
The information regarding the RAW file is at least one of the total number of the RAW files determined to be developable in the image processing apparatus and the total number of the RAW files determined to be incapable of development processing in the image processing apparatus. An image processing apparatus comprising:

  In this way, for example, the total number of RAW files that can be developed in the image processing apparatus is displayed on the display unit included in the image processing apparatus, so that the user can store a plurality of RAW files stored in the storage medium. Among them, the total number of RAW files that can be developed can be known. Therefore, when the total number is small, the user can easily determine that it is necessary to take measures such as printing after performing development processing using dedicated development software on a personal computer. Is preferred.

[Application Example 3] In the image processing apparatus according to Application Example 1 or 2,
The determination unit further includes:
The file acquired by the image processing apparatus determines whether the file is a RAW file based on the file name, and the file determined to be a RAW file is a RAW file acquired by the image processing apparatus. An image processing apparatus.

  In this way, when the image processing apparatus acquires both a RAW file and a file that is not a RAW file, the RAW file can be extracted to determine whether or not development is possible.

Application Example 4 In the image processing apparatus according to any one of Application Examples 1 to 3,
The determination unit
For each RAW file acquired by the image processing apparatus, if a part of the file name matches a predetermined character, the file information included in the RAW file is acquired and the acquired file If the information matches predetermined file information determined in advance, the image processing apparatus determines that development processing is possible, and if a part of the file name does not match a predetermined character; and An image processing apparatus, wherein even if they match, if the file information does not match predetermined file information, the image processing apparatus determines that development processing is impossible.

  In this specification, a character means the concept containing various codes | symbols and symbols, such as an alphabet, katakana, hiragana, a kanji, a number, and a symbol. The file information is a concept including various information for specifying the file format of the RAW file in the image processing apparatus, such as a camera manufacturer name, a camera model name, and a file format version name.

  For example, when RAW image data is stored in a digital camera, the file format may differ depending on the manufacturer, model, file format version, etc., even if the RAW file extension is the same. In other words, even if the extension of the RAW file is the same, there are those that can be developed by the image processing apparatus and those that cannot be developed.

  In such a case, in the image processing apparatus of this application example, for example, a file name table in which information related to a file name such as an extension of a RAW file that can be developed is described, and a model name that can be developed are described. If a model name table or the like is prepared in advance, whether or not development processing can be performed in the image processing apparatus with reference to the file name table and the model name table for a plurality of RAW files stored in the storage medium. Therefore, a more accurate determination result can be obtained.

  The present invention is not limited to the above-described aspect of the image processing apparatus, but as an aspect of a computer program for constructing the image processing apparatus, an aspect as a storage medium storing the computer program, and a RAW file information display method It is also possible to implement in various modes such as

Hereinafter, the best mode for carrying out the present invention will be described in the following order based on examples.

A. First embodiment:
A1. Configuration of First Embodiment The printer 100 is a color inkjet printer capable of direct printing. As the direct print mode in the printer 100, a “normal print mode” for printing a JPEG file saved in the JPEG format and a “RAW print mode” for printing a RAW file saved in the RAW format are prepared. Here, the RAW print mode is a mode in which RAW image data is developed and printed.

FIG. 1 is a block diagram showing a printer 100 as a first embodiment of the present invention.
The printer 100 includes a CPU 102 for performing various processes and controls according to a computer program, a memory 104, an image processing unit 106, and a USB for communicating with a USB device 200 such as a digital camera, a drive such as an HDD or a CD. The controller 108, the external memory controller 110 for reading data stored in the removable memory 300, the display panel 112 including an LCD or the like for displaying a menu or an image, a cross button or a print instruction button for operating the menu An operation panel 114 having various push buttons (not shown) such as a printer mechanism 116 that prints an image or the like on printing paper according to an instruction from the CPU 102, and a bus 120 that connects these components. The CPU 102 functions as a determination unit 122, a display control unit 124, and a print control unit 126, which will be described later, according to a computer program for a printer.
The display control unit 124 and the display panel 112 in this embodiment correspond to the display unit in the claims.

 The memory 104 is partly composed of ROM and partly composed of rewritable nonvolatile memory. The computer program for the printer is stored in the ROM. Therefore, this computer program is provided in a form recorded on a ROM chip. Further, instead of using such a ROM, a computer program for a printer is read by a CD-ROM drive device, transferred to the printer 100 via a network or the like (not shown), and written in the nonvolatile memory. Also good.

  A RAW profile 142 is stored in the rewritable nonvolatile memory. The RAW profile 142 describes data such as the extension, manufacturer name, model name, development parameter, and compression method of a RAW file that can be developed by the printer 100. Here, the development parameters are parameters necessary for developing RAW image data such as an optical black value, white balance information, color filter arrangement information of the image sensor, color space information, gradation correction information, and the like. Note that the RAW profile 142 can be updated by transferring the new RAW profile 142 to the printer 100 from a printer manufacturer's homepage or the like via a network (not shown) or the like.

  The image processing unit 106 is a processor dedicated to image processing for performing development processing on RAW image data to generate print image data suitable for printing, or to generate print image data based on JPEG data. is there. The development process is a process of unifying the number of bits, raw black correction process, white balance correction process, exposure correction process, and demosaic process on RAW image data, and then performing a series of image processing such as color reproduction process and color tone correction. That means.

A2. Operation of the first embodiment:
Now, the operation of the first embodiment will be described. For example, a user may use a compact digital camera A (hereinafter abbreviated as camera A), a single-lens reflex digital camera B (hereinafter abbreviated as camera B), and a single-lens reflex digital camera C (hereinafter referred to as camera C). And a single removable memory 300 is commonly used for the cameras A, B, and C to store the captured image data. Cameras A, B, and C can all store captured images in RAW format, and the user can store captured images in RAW format regardless of which camera is used. To do.

  When an image photographed by the camera A is saved in the RAW format, a RAW file A of the file format A is created. The RAW file A is given a file name in which an extension “AAA” is added to a numerical string that is continuous in the order of shooting. When an image captured by the camera B is saved in the RAW format, a RAW file B of the file format B is created. The RAW file B is given a file name in which an extension “BBB” is added to a numerical string that is continuous in the shooting order. When an image captured by the camera C is saved in the RAW format, a RAW file C of the file format C is created. The RAW file C is given a file name in which an extension “CCC” is added to a numerical string that is continuous in the shooting order.

  The removable memory 300 includes a raw file A having file names “0001.AAA” to “0004.AAA”, a raw file B having file names “0001.BBB” to “0007.BBB”, and a file name “0001.CCC” to Assume that a RAW file C of “0005.CCC” is stored.

  In this embodiment, the RAW profile 142 stored in the memory 104 of the printer 100 describes information about the camera A and the camera B, but does not describe information about the RAW file C. Accordingly, since the printer 100 cannot develop the RAW image data included in the RAW file C, the user cannot directly print the RAW file C using the printer 100.

  When the printer 100 is activated, the user inserts the removable memory 300 in which a plurality of RAW files A, B, and C are stored into a card slot (not shown) of the printer 100, thereby removing the removable memory 300. Is connected to the external memory controller 110, the CPU 102 recognizes the removable memory 300.

FIG. 2 is a flowchart illustrating processing for displaying the total number of RAW files that can be printed by the printer 100 on the display panel when the RAW print mode is selected.
When the user operates the operation panel 114 and selects the RAW print mode from the menu screen displayed on the display panel 112, the determination unit 122 recognizes that the RAW print mode is selected (step S102). The count value stored in the memory 104 is set to 0 (step S104). Then, extensions are extracted from the information described in the RAW profile 142 stored in the memory 104, and the extension table 144 is created (step S106). Here, since information about the RAW files A and B is described in the RAW profile 142, “AAA” and “BBB” are described in the extension table.

  Subsequently, for each RAW file stored in the removable memory 300, the determination unit 122 determines whether any of the extensions described in the extension table 144 matches the extension included in the file name of the RAW file. Whether or not is judged sequentially. Specifically, the determination unit 122 searches the plurality of RAW files stored in the removable memory 300 via the external memory controller 110 and recognizes the RAW file “0001.AAA” stored first. Then (step S108), the extension “AAA” is acquired (step S110). Then, referring to the extension table, since “AAA” is described in the extension table 144 as described above, the determination unit 122 matches the extension for the RAW file “0001.AAA”. If it is determined (Yes in step S112), the count value is incremented by 1 (ie, count value = 1), and “0001.AAA” is stored in the memory 104 as a RAW file that can be developed (step S114).

  Subsequently, when the determination unit 122 searches for the next RAW file and recognizes “0002.AAA” (Yes in step S108), the RAW file “0002.AAA” also determines that the extensions match in the same manner. The count value is incremented by 1 and stored in the memory 104. Similarly, judgment is made up to the RAW file “0004.AAA”. At this time, the count value is 4, and “0001.AAA” to “0004.AAA” are stored in the memory 104 as RAW files that can be developed. Subsequently, when the determination unit 122 searches for the next RAW file and recognizes “0001.BBB” (Yes in step S108), it similarly determines “0001.BBB”. As described above, since the extension “BBB” is also described in the extension table 144, the determination unit 122 determines that the extensions of the RAW file “0001.BBB” also match. Similarly, it is determined that the extensions of the RAW files “0002.BBB” to “0007.BBB” match, and the count value is incremented by 1 for each RAW file, and the file name can be developed. It is stored in the memory 104 as a RAW file. At this time, the count value is “11”, and “0001.BBB” to “0007.BBB” are further stored in the memory 104 as RAW files that can be developed.

  Subsequently, when the determination unit 122 searches for the next file and recognizes “0001.CCC” (Yes in step S108), the determination unit 122 similarly determines “0001.CCC”. As described above, the RAW profile 142 does not include information on the RAW file C, and therefore, the extension “CCC” is not included in the extension table 144. Therefore, the determination unit 122 determines that the extensions of the RAW file “0001.CCC” do not match. Similarly, it is determined that the extensions of the RAW files “0002.CCC” to “0005.CCC” do not match. If the determination unit 122 determines that the extensions do not match, the count value is not increased and the file name is not stored. Therefore, when the determination is made so far, the count value is “11”, and “0001.AAA” to “0004.AAA”, “0001.BBB” to “0007.” are stored in the memory 104 as RAW files that can be developed. “BBB” is stored.

  When the determination unit 122 searches for the next RAW file and recognizes that there is no next RAW file (No in step S108), the determination unit 122 causes the display control unit 124 to display an image selection screen W1 (described later). The display control unit 124 displays the count value (= 11) on the image selection screen W1 displayed on the display panel 112 (step S116).

FIG. 3 is an explanatory diagram showing an image selection screen W1 displayed on the display panel 112. As shown in FIG.
The image selection screen W1 is a screen for the user to check the image of the RAW file stored in the removable memory 300, instruct printing, and change image processing settings such as brightness. The image selection screen W1 includes a preview image display part PG, a number display part ND, a feed button B1, a return button B2, a print start button B3, and a setting change button B4.

  The preview image display unit PG reads and displays the preview image recorded in the RAW file determined to be developable, and the number display unit ND allows the displayed preview image to be developed (printable). ) Of the total number of RAW files. Further, the feed button B1 is a button for sequentially advancing the preview images to be displayed, the return button B2 is a button for sequentially returning, and the print start button B3 is a RAW print of an image displayed on the preview image display unit PG. An instruction button and a setting change button B4 are buttons for changing the image processing setting of the RAW file in which the preview image is displayed. Here, the count value (= 11) is displayed as the total number of files that can be developed (printed) in the number display section ND.

  The display control unit 124 determines that the extensions match in the above processing, and the RAW file stored in the removable memory 300 based on the file name stored as a RAW file that can be developed in the memory 104. The screen nail data included in the image selection screen W1 is acquired and displayed on the preview image display unit PG of the image selection screen W1. Here, the screen nail data is JPEG format image data generated for preview display in a digital camera. In this embodiment, it is assumed that the screen nail data is included in the RAW file.

  Thus, by displaying the total number of RAW files that can be printed (developable) in the printer 100 on the image selection screen W1, the user can determine how many of the RAW files are stored in the removable memory 300. You can know if you can print.

  Furthermore, when the user operates the operation panel 114 to change the display mode, a file selection screen W2 as shown in FIG. 4 may be displayed. FIG. 4 is an explanatory diagram showing the file selection screen W2. The file selection screen W2 includes a file name display portion FD, a preview display button B5, and a total number display portion TN. The file name display unit FD displays the file names (including extensions) of RAW files that can be developed, and the total number display unit TN displays the total number of RAW files that can be developed as the number of printable photos. To do. That is, the above-described count value is displayed on the total number display unit TN. When the user selects a desired file and selects the preview display button B5, a preview image (not shown) is displayed. Note that the RAW file determined to be developable by the determination unit 122 can be developed and printed by the printer 100, so that the user can select “printable RAW file” on the file selection screen W2. Is easy to understand.

As described above, the file name (including the extension) of the RAW file determined to have the same extension by the determination unit 122 is stored in the memory 104 as a RAW file that can be developed. The display control unit 124 reads the file name of the RAW file that can be developed from the memory 104 and displays it on the file name display unit FD of the file selection screen W2. That is, “0001.AAA” to “0004.AAA” and “0001.BBB” to “0007.BBB” are displayed in the file name display portion FD.
Further, the display control unit 124 reads the count value (= 11) stored in the memory 104 and displays it on the number display unit TN of the display panel 112.

  Thus, when the file name of a RAW file that can be developed (printed) is displayed, the user operates the operation panel 114 to display a preview image by selecting a desired file name. Or printing can be instructed. Further, for example, the user can recognize the difference in the extension and identify which camera has taken the image.

  When confirming the preview image of each RAW file on the image selection screen W1 and printing the RAW file “0001.AAA”, the user displays the RAW file on the preview image display unit PG of the image selection screen W1. When the preview image “0001.AAA” is displayed and the print start button B3 is selected, the print control unit 126 transmits the RAW image included in the RAW file “0001.AAA” from the removable memory 300 via the external memory controller 110. The data is transferred to the memory 104, and the image processing unit 106 is instructed to perform image processing. The image processing unit 106 performs development processing on the RAW image data based on the development parameters included in the RAW profile stored in the memory 104 to generate image data for printing. When the image processing unit 106 outputs the image data for printing to the printer mechanism unit 116, the printer mechanism unit 116 prints the image of the selected RAW file “0001.AAA” on the printing paper.

B. Second embodiment:
Subsequently, a second embodiment will be described. Since the printer of the second embodiment has the same configuration as the printer 100 of the first embodiment, the description of the configuration is omitted. In this embodiment, the total number of RAW files that cannot be developed is displayed as the count result (step S116). Since the other processes are the same as those in the first embodiment, Description of common processing is omitted. Also in the present embodiment, as in the first embodiment, the user performs shooting using the camera A, the camera B, and the camera C, and the single removable memory 300 is stored in the cameras A, B, and C. It is assumed that the captured image data is stored in common use.

  When the removable memory 300 is inserted into a card slot (not shown) of the printer and connected to the external memory controller 110, the CPU 102 recognizes the removable memory 300 and calculates the total number of RAW files stored in the removable memory 300. Counting is performed, and the total number of RAW files is stored in the memory 104 (“16” in this embodiment). As a result of the determination unit 122 repeating steps S108 to S114 for all the RAW files stored in the removable memory 300 and determining whether or not development processing is possible in the printer, the count value is “11”. The determination unit 122 counts the value “5” obtained by subtracting the count value “11” from the total number of RAW files (“16”) stored in the removable memory 300, that is, the total number of RAW files that cannot be developed. Is displayed on the display panel 112 (step S116).

  In this way, the user can know the total number of RAW files that cannot be printed (development processing is impossible). Therefore, if the total number of RAW files that cannot be printed is large, the computer performs development processing. Then, after saving in the JPEG format, it is possible to take measures such as printing a JPEG image on the printer.

C. Third embodiment:
Subsequently, a third embodiment will be described. Since the printer of the third embodiment has the same configuration as the printer 100 of the first embodiment, description of the configuration is omitted. In this embodiment, the total number of RAW files that cannot be developed is displayed together with the total number of RAW files that can be developed as a count result (step S116). That is, the processing after step S112 is different, but the other processing is the same as that of the first embodiment, and therefore description of processing that is common to the first embodiment is omitted. Also in the present embodiment, as in the first embodiment, the user performs shooting using the camera A, the camera B, and the camera C, and the single removable memory 300 is stored in the cameras A, B, and C. It is assumed that the captured image data is stored in common use.

  FIG. 5 is a flowchart showing processing for displaying on the display panel the total number of files that can be developed and the total number of files that cannot be developed in the printer of this embodiment. In this embodiment, when the user selects the RAW print mode, the determination unit 122 recognizes that the RAW print mode is selected (step S102), and the count value N1 and the count value stored in the memory 104 are recognized. N2 is set to 0 (step S104). Thereafter, similarly to the first embodiment, the processes of steps S106 to S112 are performed. In step S112, when the extension of the RAW file matches one of the extension tables (Yes in step S112), the count value N1 is incremented, and the file name is stored as a RAW file that can be developed. It memorize | stores in 104 (step S114). On the other hand, if the extension of the RAW file does not match any of the extension tables in step S112 (No in step S112), the count value N2 is increased and the file name is changed to a RAW file that cannot be developed. The file is stored in the memory 104 (step S115).

  Then, as in the first embodiment, for each RAW file stored in the removable memory 300, Steps S108 to S114 (or Step S115) are repeated to determine whether or not development processing is possible in the printer. Count that number. When the determination is completed for all RAW files (No in step S108), the count value N1, the total number of RAW files that can be developed in the printer, the count value N2, and the RAW file that cannot be printed by the printer are displayed. The total number is displayed on the display panel 112 (step S116).

  FIG. 6 is an explanatory diagram showing a file information display screen W3 displayed on the display panel 112. As shown in FIG. The file information display screen W3 is a screen for the user to check the files that can be printed by the printer of this embodiment and the files that cannot be printed among the RAW files stored in the removable memory 300.

  The file information display screen W3 includes file name display portions FD1 and FD2 and a preview display button B5. The display control unit 124 reads the file name of the RAW file that can be developed from the memory 104 and displays it on the file name display unit FD1 of the file information display screen W3. Further, the display control unit 124 reads the count value N1 (= 11) stored in the memory 104 and displays it as the total number of printable RAW files on the file name display unit FD1 of the file information display screen W3 (in the drawing). N1).

  Similarly, the display control unit 124 reads the file name of the RAW file that cannot be developed from the memory 104 and displays it on the file name display unit FD2 of the file selection screen W2. Further, the display control unit 124 reads the count value N2 (= 5) stored in the memory 104 and displays it as the total number of RAW files that cannot be printed on the file name display unit FD2 of the file information display screen W3 (FIG. 5). N2).

  By doing so, the user can select both the number of RAW files that can be developed and printed by the printer and the number of RAW files that cannot be printed out of the RAW files stored in the removable memory 300. Can be confirmed. Therefore, a printable file is printed as it is by a printer, and a non-printable file is processed by a computer and saved in JPEG format, and then a JPEG image is printed by the printer. Will be able to.

D. Fourth embodiment:
Subsequently, a fourth embodiment will be described. Since the printer of the fourth embodiment has the same configuration as the printer 100 of the first embodiment, description of the configuration is omitted. In this embodiment, the user takes a picture using the cameras A and B and the compact digital camera D (hereinafter abbreviated as the camera D), and uses a single removable memory 300 for the cameras A, B, and D. In common, it is assumed that the captured image data is used and stored. The camera D is a camera made by the same manufacturer as the camera B. When the captured image is saved in the RAW format, a RAW file D of the file format D is created. The RAW file D is given a file name in which the extension “BBB” is added to “C + serial number” in the shooting order. For example, the RAW file D of the first photographed image is “C0001.BBB”. The RAW files A, B, and C include file information such as manufacturer name, model name, and version name.

  The removable memory 300 includes RAW file A “0001.AAA” to “0004.AAA”, RAW file B “0001.BBB” to “0007.BBB”, and RAW file C “C0001.BBB”. To “C0005.BBB” are stored.

  In the RAW profile stored in the memory 104 of the printer according to the present embodiment, information regarding the cameras A and B is described as in the first embodiment, but information regarding the RAW file D is not described. . Accordingly, the RAW files A and B can be directly printed by developing the RAW image data included in the RAW files A and B with the printer. Since development processing cannot be performed, direct printing cannot be performed. However, since the extension is “BBB”, which is the same as that of the RAW file B, it is not possible to determine whether or not development processing is possible in the printer simply by looking at the extension. The operation of the printer of the fourth embodiment for solving this problem will be described below.

FIG. 7 is a flowchart showing processing for displaying the total number of RAW files that can be developed in the printer on the display panel.
When the user operates the operation panel 114 and selects the RAW print mode from the menu screen displayed on the display panel 112, the determination unit 122 recognizes that the RAW print mode is selected (step S202). The count value stored in the memory 104 is set to 0 (step S204). Then, the extension and the model name are extracted from the information described in the RAW profile 142 stored in the memory 104, and a file information table is created (step S206). As described above, since information about the RAW files A and B is described in the RAW profile 142, the file information table includes “AAA” and “BBB” as extension information, “Camera A” as model information, “Camera B” is described.

  Subsequently, for each RAW file stored in the removable memory 300, the determination unit 122 determines whether any of the extensions described in the file information table matches the extension attached to the RAW file. If it is determined that they match, it is further determined whether or not the model information included in the RAW file matches the extension described in the file information table.

  Specifically, the determination unit 122 searches the plurality of RAW files stored in the removable memory 300 via the external memory controller 110 and searches the RAW file A “0001.AAA” stored first. Is recognized (Yes in step S208), the extension “AAA” is acquired (step S210). When the determination unit 122 refers to the file information table, as described above, “AAA” is described in the file information table, the determination unit 122 determines that the RAW file A “0001.AAA”. , It is determined that the extensions match (Yes in step S212).

  When the extension matches the extension described in the file information table, the determination unit 122 uses the model name included in the RAW file A “0001.AAA” stored in the removable memory 300 via the external memory controller 110. When a certain “camera A” is acquired (step S214) and the file information table is referenced, as described above, since “camera A” is described in the file information table, the RAW file A “0001.AAA” is obtained. Determines that the model names match (Yes in step S116). As in the first embodiment, the count value is increased and “0001.AAA” is stored in the memory 104 as a RAW file that can be developed (step S118). Similarly, for the RAW files “0002.AAA” to “0004.AAA” and the RAW files B “0001.BBB” to “0007.BBB”, the extensions and model names are acquired and stored in the file information table. It is determined whether or not it matches what is described.

  As described above, various information about the RAW files A and B are described in the RAW profile, and “AAA”, “BBB”, “Camera A”, and “Camera B” are included in the file information table. Thus, the determination unit 122 determines the same as in the case of the RAW file A “0001.AAA”, increments the count value by 1 for each file, and stores the file name in the memory 104 together with the extension. Remember. At this time, the count value is “11”, and “0001.AAA” to “0004.AAA” and “0001.BBB” to “0007.BBB” are stored in the memory 104 as RAW files that can be developed. Yes.

  Subsequently, when the determination unit 122 searches for the next file and recognizes “C0001.BBB” (Yes in step S208), the determination unit 122 acquires the extension of the RAW file D “C0001.BBB” (step S210). Judgment. Referring to the file information table, as described above, since “BBB” is described in the file information table, the determination unit 122 determines that the extensions of the RAW file D “C0001.BBB” match. (Yes in step S212). Since the extension matches the extension described in the file information table, the determination unit 122 uses the model name included in the RAW file D “C0001.BBB” stored in the removable memory 300 via the external memory controller 110. When a certain “camera D” is acquired (step S214) and the file information table is referenced, as described above, since “camera D” is not described in the file information table, the RAW file D “C0001.BBB” Determines that the model names do not match (No in step S216). Similarly, the RAW files D “C0002.BBB” to “C0005.BBB” are determined to have the same extension but not the same model name.

  If the determination unit 122 determines that the model names do not match, the count value is not increased and the file name is not stored. Therefore, when the determination is made so far, the count value is “11”, and “0001.AAA” to “0004.AAA”, “0001.BBB” to “0007.” are stored in the memory 104 as RAW files that can be developed. “BBB” is stored.

  When the determination unit 122 searches for the next RAW file and recognizes that there is no next RAW file (No in step S208), the determination unit 122 causes the display control unit 124 to display the image selection screen W1 (FIG. 3). The display control unit 124 causes the count value (= 11) to be displayed on the image selection screen W1 (FIG. 3) displayed on the display panel 112 (step S220).

  In the present embodiment, the display panel 112 displays an image selection screen W1 shown in FIG. 3 as in the first embodiment. The count result is displayed as the total number of printable files in the number display section ND.

  As described above, according to the printer of the present embodiment, not only the extension but also the model name is referred to determine whether the printer can perform development processing, and the total number of RAW files that can be developed can be directly printed. The total number of RAW files that can be displayed is displayed on the display panel 112. Therefore, the user can know the total number of RAW files that can be directly printed. Therefore, for example, when the number of RAW files that can be directly printed is small, it is easy for the user to take measures such as printing after performing development processing using dedicated development software on a personal computer. Therefore, it is preferable.

E. Modifications The present invention is not limited to the above-described embodiments, and can be implemented in various modes without departing from the scope of the invention.

  (1) In the above-described embodiments, a printer that can perform development processing on RAW image data has been described. However, the present invention performs development processing on RAW image data such as a personal computer with a display or a photo storage. The present invention can be applied to various image processing apparatuses that can be applied. In addition, when the present invention is applied to a printer, it can be applied not only to a home printer but also to various printers such as a relatively high-function printer system for business use. Further, the present invention can be applied to a multifunction machine having a scanner function and the like.

  (2) In the above-described embodiment, whether or not development processing is possible in the printer 100 is determined based on the extension included in the file name of the RAW file, but other information included in the file name includes A determination may be made based on this. Further, it may be determined including other than the match with the table. For example, when a file name is given to RAW image data in a digital camera, manufacturer A adds “A” to the beginning of the file name, and manufacturer B adds “B” to the beginning of the file name, followed by four digits. Suppose that there is a rule of serial numbering. In such a case, based on the letter at the beginning of the file name (including numbers and symbols), does the file name begin with “A” or does the file name begin with “B”? If “B” is added, it can be determined whether the printer 100 can perform development processing based on whether or not a 4-digit number follows.

  (3) In the above embodiment, the case where only the RAW file is stored in the removable memory 300 is illustrated, but an image file other than the RAW file (for example, a JPEG file) is also stored together. Also good. In such a case, the determination unit 122 may determine whether or not the file in the removable memory 300 is a RAW file.

  For example, when the user inserts the removable memory 300 into a card slot (not shown) of the printer 100 and the removable memory 300 is connected to the external memory controller 110, the determination unit 122 is stored in the removable memory 300. If the extension is “JPEG”, the file name is stored in the memory 104 as a JPEG file. When the extension is not “JPEG”, it may be determined whether or not the RAW file is a RAW file that can be developed by referring to the extension table as described in the above-described embodiment. . Note that not only “JPEG” but also “GIF”, “BMP”, and other saved files that can be printed without performing development processing on image data are determined not to be RAW files. Also good. On that basis, a file in a storage format that does not need to be subjected to development processing such as “JPEG” may be counted and displayed. In this way, the user can grasp the number of images that need not be developed, the number of images that need to be developed, and the number of images that cannot be handled by this apparatus.

  (4) In the above-described embodiment, when the extension of the RAW file stored in the removable disk 300 does not match any of a plurality of extensions described in the extension table or the file information table, In the printer, the determination unit 122 determines that development processing cannot be performed. However, a function of updating an extension table or the like may be provided. For example, if the extensions do not match, a help screen for updating the RAW profile may be displayed on the display panel 112. When the user operates according to the instructions described on the help screen displayed on the display panel 112, a new RAW profile can be downloaded from the home page of the printer manufacturer, and the RAW profile provided in the printer can be updated. By doing so, it is possible to increase the number of RAW files that can be developed in the printer (that is, capable of direct printing).

  In addition to updating the RAW profile, a program for causing the image processing unit 106 to execute development processing and other image processing may be provided. For example, as in the case of updating the RAW profile, a help screen for updating the image processing program is displayed on the display panel 112, and the user updates the image processing program in accordance with the instruction so that the same as described above. The number of RAW files that can be directly printed by the printer 100 can be increased.

(5) In the above-described fourth embodiment, when the extension matches the extension described in the file information table, the RAW that can be developed in the printer with reference to the model name included in the RAW file. Although it has been determined whether the file is a file, the determination may be made based on other information such as a file format version name and manufacturer name.

In addition, whether to check the file information for each extension is linked, and even with the same extension, files that can be developed and files that cannot be processed may be mixed Only the file information may be confirmed. For example, in the above-described fourth embodiment, the file information is not confirmed when the extension is “AAA”, and the file information is confirmed when the extension is “BBB”. And the extension is "AAA"
If so, the confirmation of the file information can be omitted. Therefore, the processing time can be shortened.

(6) For each RAW file stored in the removable memory 300, it is determined whether or not development processing is possible in the printer 100, and processing for counting the total number of RAW files that can be developed (steps S104 to S114 in FIG. Steps S204 to S in FIG.
218) may be performed before the user selects the RAW print mode. In this way, when the user selects the RAW print mode, the display control unit 124 only needs to read and display the count value written in the memory 104. Therefore, after the user selects the RAW print mode, The processing time until the count result is displayed on the display panel 112 is shortened. Therefore, the user can quickly know the total number of RAW files that can or cannot be developed in the printer.
